Subject: [PATCH] vbo: change an argument in vbo_draw_indirect_prims()
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

In vbo_draw_indirect_prims() pass the 'indirect_data' argument to
vbo->draw_prims().  All the callers are passing ctx->DrawIndirectBuffer
so this should be no functional change.  Add a (temporary) assertion to
be sure.
